Abstract

The invention designs an optimal station state management method based on satellite channel contention. The optimal station state management method is applied to an FDMA satellite communication network, a network management channel applies network management of a TDM / ALOHA communication system, an optimal station state management method is provided, and effective management for the station state in the satellite communication network is achieved. According to the invention, the state of stations in the satellite communication network can be effectively managed, preferentially polling the station state which is the most required to be queried according to an optimal query strategy, simultaneous transmission of state query messages in the ALOHA channel can be effectively avoided, the utilization rate of the ALOHA channel can be effectively improved, and the accuracy and real-time performance of station state management are effectively improved.

Description

technical field [0001] The present invention relates to the technical field of satellite communication, especially focuses on the network management technology based on satellite contention channel, and specifically relates to how to efficiently manage the state of the network management station. Background technique [0002] At present, the network management channel of the domestic FDMA satellite communication network generally adopts the TDM / ALOHA communication system. The network management center sends forward signaling through the TDM channel, and the network management station sends the return information through the ALOHA channel, and the network management stations compete for the ALOHA channel. Traditional station status management confirms the peer station status through point-to-point query / response messages, and performs site status management based on point-to-point status query results. Under the TDM / ALOHA communication system, the network management station c...
